Put the numbers in a regular multiplication set and multiply by going down each column (first only use the number in the ones place that is on the bottom) then when you do that put a zero in the ones place on your product then do the other number

Example 20 x 30 is similar to 3x2 which is 6. Just add the zeroes on the end: 600
